Mini Grand Piano that got past our freight system and no union help because it wasn't labeled properly and boss said it's close to 70lbs. The elderly lady needed it in her living room that was up her porch stairs and I told her we're not allowed to go in her house & even if I could I can't lift this alone. She said her son will be home in 30-minutes. I said I will leave it right here in your patio because I can't wait 30. She said, ok, but you come back. I said sorry, I only have 5-stops left and my day is done. So I left & she called in a complaint. Boss made me go back the next day and help her son drag it in her living room.
Worse repetitive package for me was Live Crickets in the summer. Trucks get POW Prisoner Box hot and crickets would go mad and

& piss to a suffering death and your package area would be covered in cricket dustings/feces. The smell was rough enough but I am convinced inhaling that 'insect dust' over the years caused terrible breathing problems to this day I deal with along with other dust and airborne particles from packages.
So you drivers/loaders out there working the distance long-term at UPS keep that in mind. I know a lot of retirees from UPS with lung issues. CPAP machines etc... of course it also relates to life style too. Stress, obesity, smoking/chew, genetics but after this virus is gone. It wouldn't hurt to always carry a N95 mask in your package car to sort or for those long dusty roads.
